Severus I
Two months into Severus’ first year at Slytherin house, a panicked fifth year bursts into his office around two in the morning. His name is Yve and he remembers him from his advanced potions class, long hair never tied back and always getting into his work. He has his hair up, and obviously is missing a few glamours because Severus realizes this student must be transgender. Has he had no one to ask for help on that? Strange.
“Mr Leblanc, do you have a reason for coming into my office at this hour?” he asks. For the first year, he is the dungeon bat to the Slytherins, too. He assumes he’s the only one in the house wearing a mask, or at least that if he wasn’t he’d notice.
The boy is crying. “I,” he says, “I’ve been vomiting a lot,” he says. The next thing he says is too badly garbled by his sobs for Severus to hear clearly.
“I’m sorry, Yve, you must speak clearer for me to be able to understand you,” he says, much more gently. He notices, and looks at him, surprised. He realizes this is the first time that Yve has looked at him in the face this entire encounter.
“I,” he says, taking in a shuddering breath, “I think I might be pregnant, and I don’t know why, really. We only did it once, too, before he started going with Bryce. I don’t- I don’t know,” he says. “I don’t know who else to tell. No one knows that I have the wrong bits except him, and the sorting hat, who called my real name which was really nice of it but now I don’t know, I don’t know.”
Severus stands, “I know a spell to check, would you like if I tried it on you?” he asks, and he nods. He points his wand at Yve and goes through the incantation, deliberately pronouncing it in such a way to make it easily replicable if necessary. His wand emits a blue light, “You’re not pregnant,” he says, “but... my apologies but you are aware that it is possible to become pregnant any time individuals with the appropriate bits have sex, yes?” he asks.
Not that there was a sex ed course in his days at Hogwarts but he’d assumed his students, especially his older students, would be much better informed about it.
“No,” he says, looking down, “I didn’t know. No one told me.”
“That is something I will need to fix, then,” Severus says. “Will you be alright?” he asks, and he nods.
“Thank you sir,” he says. “And for continuing to think I’m a guy.
He turns to leave, and Severus says, “Mr. Leblanc, if you, or any other transgender student in my house, need any help, I will do my best.”
The boy nods, and leaves, shutting the door behind himself.
Severus sinks into his seat and makes a mental note to continue looking into that safe binding charm he had begun years ago in his sixth year.
